摘要： A structure body cutting system includes a cutter system mounted on a cutting side trailer and configured to cut a blade to be cut, and a feeder system mounted on a feeding side trailer and configured to send out the blade to the cutter system. The blade is placed so as to straddle between the cutter system and the feeder system. The feeder system sends out the blade to the cutter system as the feeding side trailer comes close to the cutting side trailer. The cutter system cuts the blade into a plurality of cut segments by cutting the blade sent out from the feeder system.

摘要： A band saw machine for sawing metallic workpieces, having a lower saw part and an upper saw part with two carrying wheels mounted therein, and a saw band that revolves with a cutting motion around the wheels that passes through a cutting region. A feeding device attached to the lower saw part feeds workpieces to the cutting region and/or into a sawing plane, in which the cutting region of the saw band is moved in a saw advance motion. The feeding device has a movable holder for detachably fastening the workpiece, and the holder, starting from an initial position, is movable both with translational and rotational motions. The saw band is guided through the cutting region, and the holder is moved translationally against the cutting region in order to execute the saw advance motion. Here, the workpiece is preferably turned by the holder such that its upper side faces downward.

摘要： A method for controlling a sawing machine is provided. For a first cut in a workpiece, a working feed rate that is specific to the workpiece geometry, the workpiece material and the sawing tool is defined in advance. During the first cut, an instantaneous value of a physical variable is determined at a frequency converter, that is related to the torque transmitted by the sawing tool drive to the sawing tool, and this value is transmitted as an instantaneous torque value to a machine controller. The instantaneous torque value is continuously evaluated, a maximum torque value of the first cut is determined and a maximum value for the torque value is defined based thereon. For subsequent cuts in the same workpiece, the working feed rate is regulated, using the instantaneous torque value as a regulating variable, such that the instantaneous torque value is kept constant, close to the maximum valve.

摘要： A feed/clamp apparatus includes a feed vise mechanism provided upstream from a cutting position, and a downstream vise mechanism provided just downstream from the cutting position. The feed vise mechanism includes first/second feed vise jaws, a downstream moving cylinder for moving the first feed vise jaw, and a downstream shifting cylinder for shifting the second feed vise jaw. The downstream vise mechanism includes first/second downstream vise jaws, a downstream moving cylinder for moving the first downstream vise jaw, and a downstream shifting cylinder for shifting a second downstream vise jaw. A vise surface of the second downstream vise jaw is located on one side of the vise reference position when the downstream shifting cylinder is located its stroke end on the one side. A thrust force of the downstream shifting cylinder toward the one side is made equal to a thrust force of the downstream moving cylinder toward another side.

摘要： A sawmill feedspeed control system having a force sensor operatively coupled to a sawguide of a sawblade, the output of the force sensor being processed and supplied to a motion controller and driver for reducing or increasing feed velocity of a workpiece so as to prevent overfeed or underfeed, while minimizing deviations of the blade from a straight cut and maximizing production throughput.

摘要： There is provided in a preferred embodiment an apparatus for feeding an elongated material in a direction substantially generally along a length thereof to a cutting device having a cutting surface. The apparatus includes a lifting base assembly and a material shuttling assembly secured on the pivoting base assembly, the latter defining a feeding path. The lifting base assembly has a lower base portion and an upper base portion hingedly coupled to the lower base portion along a base pivoting axis generally parallel to and laterally offset from the feeding path. The upper base portion is selectively rotatable about the pivoting axis relative to the lower base portion between a level position and a lifted position, wherein in the lifted position, the material is raised above the cutting surface in an angled orientation where the material is further raised along a first lateral end portion relative to a second lateral end portion opposed to the first lateral end portion, the second lateral end portion being proximal to the pivoting axis.

摘要： A machine including: a table having a surface adapted to have a workpiece lay and move thereon, and a vise for gripping the workpiece. The machine also includes a drive system for moving the vise and workpiece a distance along the table surface, and a sensor assembly connected to the vise for measuring an amount of slip distance occurring between the vise and the workpiece. The machine also includes a control unit connected to the sensor assembly and the drive system for storing the measured slip distance and for operating the drive system and for operating to do at least one of, when a predetermined amount of slip distance is detected: sounding an alarm and stopping further movement of the workpiece, and, when a slip distance is measured, for causing the drive system to move the vise and workpiece an added distance equal to the measured slip distance.
